A GUEST on Antiques Roadshow broke down in tears as she learned the true value of her painting.
The contributor appeared on the PBS version of the show in the United States after she hung her artwork on her wall for 40 years.
Before coming on the programme, she watched previous episodes of Antiques Roadshow which featured a similar piece.
She wanted to know if her heirloom could be the real deal as she explained: "I was watching Antiques Roadshow and in the feedback booth, a gentleman stated that he found out his Edouard Cortez was a fake and a light bulb went off.
"I ran downstairs and sure enough, this painting that had been hanging on our wall for 40 years said Edouard Cortez."
She explained she learned about the artist of the portrait online after her grandparents were both artists.

However it was the hole that made the vendor think that the artwork was indeed genuine.
He said: "If you look at the lines, they all converge and come to this point.
"Now that, of course, is not conclusive but there's a gallery in New York and there's another gentleman who will authenticate this works.
"But I think there's no question that this work is in fact by Edouard Cortez. For an 18 by 22-inch canvas at auction, that should be worth $30,000 to $50,000."
The guest appeared excited as she burst into tears as the expert interjected: "I hope those are tears of joy by the way."
She replied: "They are tears of joy."
